GAS-PRODUCER.

Specification of Letters Patent.

Patented J me 4, 1997.

Original application filed February 7,1905, Serial No. 244,617. Divided and thisapplication filed February 19,1906. Serial To all whom it may concern:

' Be it known that we, Armin DE GALOCSY, metallurgical and civil engineer, LADISLAS DE BANo, mechanical and civil engineer, and JOHN T RENY, metallurgical and Hungarian State engineer, of Budapest, Austria-Hungary, have invented certain new and useful Improvements in Gas-Producers, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates togrates and especially to helical grates and is a division of our application 244,617 filed February 7, 1905 for gas producers.

The accompanying drawing illustrates an embodiment of this invention in vertical section.

In the illustrated embodiment of this invention the helical grate B is shown in operative position with the gas generator chamher A of a gas producer. This chamber A is mounted on an iron or steel ring 1 which is so shaped as to serve as a water seal 2 for the gas generator. A suitable ash receiving basin 3 is formed on one side of the waterseal to receive the slag and ashes falling from the grate B and a suitable bucket elevator 4 working in this basin operates in an obvious manner to continuously remove this waste material and load it on the cars 11 as indicated. The helical grate B is keyed to. the vertical shaft 5 by the key 12. This shaft passes down through a stufling box 6 in the water seal and is supported on a step bearing 7 beneath the water seal. The grate may be rotated in either direction by the worm Wheel 8, keyed upon the shaft 5 by means of the key 9, and in mesh with the worm 10 which may be operated in either direction by any suitable power.

In the operation of the devices showncoal is fed in the hopper D which may be closed by a suitable device, such as a belLG and falls upon the helical grate B. The coal burning upon this surface forms gas in an obvious manner which is drawn off through the ort 12 and flows into the gas main 13 which is controlled by a suitable valve, such as 14. To assist in the production of gas, a fan C is used having an intake f and an outlet f beneath the grate B but above the water of the water seal as shown. This feature, however,

may be omitted if desired.

The grate B is normally rotated at sucha rate of speed that merely ashes and" slag are discharged from it into the water of the water seal. The ashes and the slag falling u on the surface 14 is forced over by the a dle 15, which is secured to the under su ace of the grate B by rivets 17 or other suitable means, into-the opening 16 of the basin 3.

In gas producers the coal frequently cokes to a. considerable extent forming an'arch extending from the sides of the generator to the center and preventing very largely the successful operation of the gas producer. By using thehelical grate of our invention the coal, coke and slag within the roducer A can be agitated and the crown o coke and slag broken up by running the helical grate B in such a direction that the ashes and slag are not discharged from the bottom of the chamber, but is merely given an intermittent vertical movement. rotated in the usual or discharge direction the ashes are regularly discharged from the lower end of the generator chamber and as the grate must make a complete revolution before the material first separated fi'om the bottom of the coal bed is discharged from the grate sufficient time elapses for its com lete combustion and the coal is thus abso utely burned out before the slag and ashes drop into the water seal where they serve to generate steam to a considerable extent.

While I have shown the helical grate in connection with a gas producer it is of course not limited to such use as it is adapted for general application.

Without limiting ourselves to the exact details of the disclosure in this case What we claim as our invention is:

1. In gas producers, a generator chamber,

When the helical grate is 1 portion of the chamber, a helical grate clos- 'ing the lower portion of the chamber, and

means for rotating the grate in either direction for the purpose specified.

2.- In gas producers, a generator chamber,

means for feeding material to the upper por-- tion of the generator chamber, a helical grate mounted beneath the chamber, an ash pit beneath the helical grate, having an ash re- IOO ' .ceiving'basin and a paddle secured to the grate adapted to force the ashes from the higher portion of the ash pit into the discharge basin'for the purpose specified.

3. In gas producers, a generator chamber, means for feeding material to the upper portion of the chamber, a helical grate mounted beneath the chamber and of substantially the same cross-section, a ring connected to and extending downward from the chamber forming a Water seal, for the purpose specified.

4. In gasproducers, a generator chamber, a ring upon which it is mounted and which is adapted to form a water seal for the generator chamber, means-for feeding material intothe upper portion of the generator chamber, a helical grate mounted beneath the chamber and within the ring and of substantially the same cross-section as the chamber, an ash receiving basin, 8. vertical shaft upon which the helical grate is mounted, and

means for rotating the same in either direc tion for .the purpose specified.
